Understanding the occurrence of flow liquefaction requires knowledge of the sub-surface condition controlling its occurrence. This paper presents the results of seismic refraction surveys conducted to evaluate the sub-surface geological condition in the Sibalaya flow liquefaction area. From the interpretation of the seismic refraction model, an inclined boundary presents between the near-surface sediment layers. Further examinations of the SRT images demonstrate the existence of localized basinal structures in the rock layer with the highest P-wave velocity. The basinal structure may be associ

Abstract A big earthquake may induce flow liquefaction phenomena in lowland areas made up of sedimentary deposits.

This study integrates field observations, structural analysis, and drillhole data to model the complex fault networks within Shizidun tungsten deposit in the central-northern Yangtze Block of South China Craton by using ArcGIS and Leapfrog software.  Surface mapping revealed small-scale faults with diverse orientations, including ENE-, NW-, and N-S-trending faults,  while subsurface modeling using drillhole data identified a network of steeply dipping faults intersecting within a Neoproterozoic granitic pluton which was intruded by Mesozoic granites. The results highlight a structura

AbstractGeoscientific evidence shows that various parameters such as compaction, buoyancy effect, hydrocarbon maturation, gas effect and tectonic activities control the pore pressure of sub-surface geology. Spatially controlled geoscientific data in the tectonically active areas is significantly useful for robust estimation of pre-drill pore pressure. The reservoir which is tectonically complex and pore pressure is changing frequently that circumference motivated us to conduct this study. The changes in pore pressure have been captured from the fine-scale to the broad scale in the Jaisalmer su
